CUPOLA-BOTTING APPARATUS.

Application filed April 1926. Serial no. 103.863.

The object of my said invention is the provision of a cupola botting apparatus i. e., an apparatus for enabling an operator to expeditiously and easily closethe opening in a cupola and this against the action of molten metal flowing I through said opening and without liability of the operator being injured by splashes of molten metal, the apparatus being designed to be securely'anchored in spaced relation in front of the cupola opening so that the apparatus will be entirely out of the way when not in use.

Other objects and practical advantages of the invention will be fully understood from the following description and drawings when the same are read in connection with the drawings, accompanying and forming part of this specification, in which Figure 1 is a side elevation, partly in section, of the preferred embodiment of my invention as the same appears when the bott stick is in retracted, idle position.

Figure 2 shows the apparatus inside elevation with the bott stick extended, and also shows the apparatus in proper relation to the opening of a cupola and makes clear the use of the apparatus in the closingof the said cupola opening.

Figure 3 is ahorizontal section taken on the line 38 of Figure 1, looking downwardly.

Figure 4 is a transverse section taken in the plane indicated by the line 4-4 of Figure 1, looking toward the, left.

Figure 5 is a detail perspective showing the bott stick per se.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

In Figure 2, I show a cupola 1, with the conventional opening 2, and in said Figure 2, I show the relation of my novel apparatus to the cupola.

'My invention contemplates the secure anchoring or fixing of the main frame of the apparatus in spaced relation to the cupola 1 and with the bott stick 3 of my apparatus alined with the center of the opening 2 so that when the bott stick is advanced to plug the opening 2 through the medium of mud or other appropriate substance 4 applied to the head 5 of the stick 3, the mud will occupy and seal the opening 2 and will be strongly held in the opening 2 against the action of molten metal tending to flow through the said opening 2.

.In addition-to the bott stick 3, my apparatus comprises a main frame 6- and manually operable means for advancing and retract ing the bott stick. The main frame 6 may within the purview of my invention, be constructed in any approved manner. I prefer, however, to have the said mainframe comprise end uprights 7 of inverted U-shape, a body bar 8 fixed at 9 with respect to the uprights 7 and having a longitudinal bore 10 for the reception and guidance of the stick 3 and also having a longitudinal slot 11 below .and in communication with the said bore 10 for the play of the pendent arm which is arranged in the bifurcation of the arm 12 and is pivotally connected to said arm 12 so that swinging movement of the members 16 will be attended by rectilinear movement of the stick 3. One of the trunnions 15 alluded to is also fixed to a crank 18, and pivotally connected at 19 to the crank 18 is a rectilinearly movable handle 20 with an angularly disposed hand grasp .21 at its rear end; the said handle or handle rod 20 being mounted and movable in a fixed guide 22 on the rear upright 7 of the main frame. At 23 the main frame is preferably, though not necessarily, equipped with a mud and sponge board or rest for the convenience of the operator of the apparatus.

Also in accordance with my invention the main frame is provided at its rear end with a guard 24 which may be and preferably is in the form of a sheet of metal and is designed to rest in front of the operative and to prevent injury to the operative from sparks of iron or splashes of molten metal.

In Figure 1, my novel apparatus is shown with the bott stick 3 retracted, andtherefore it will be understood that when the stick 3 is in said position and the head5 of the stick is supplied with wet mud, and the stick is advanced as shown in Figure 2, the opening 2 of the cupola 1 will be plugged by the mud,

and this effectually, notwithstanding the tendency of molten metal to flow out through 1 the opening 2.

Manifestly the advancing of the bott stick 3 is brought about by the manual movement of the handle rod 20 from the position shown in Figure 1 to that shown in Figure 2, and from this it follows that when the handle rod 20 is manually moved forwardly, the bott stick 3 will be retracted, i. e., moved from the position shown in Figure 2 to that shown in Figure 1. In the latter position the bott stick will 'be out of the way of a person walking or working adjacent to the cupola.

l lotwithstanding the facility with which the opening 2 of the cupola may be closed through the medium of my novel apparatus, it will be appreciated that the apparatus is simple and inexpensive in construction and is further advantageous because it renders it-feasible for an operative to quickly close the cupola opening 2 Without subjecting the operative to the danger of being burnt or otherwise injured by metal emitted from the cupola.

I have enteredinto a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment. I do not desire, however, to he understood as limiting myself to the construction and arclaim and desire to secure by Letters-Patent,

1. In combination, a frame, a bott stick carri d and guided by the frame, a longitudinally movable handle rod carried by the frame, swingable members mounted in the frame, one of said members being equipped with a crank in pivotal connection with said rod, and a link interposed between and connected withthe swingable members and the stick.

2. In combination, a frame, a bott stick carried and guided by the frame, a longitudinally movable handle rod carried by the frame, swingable members mounted in the frame, one of said members being equipped with a crank in pivotal connection with said rod, and a link interposed between and connected with the swingable members and the stick; the said frame being equipped with a g rd, and the said handle rod being mov-' able alongside said guard.

In testimony whereof I afliX my signature JAMES MAYES.
